Page36 4 OPERATING INSTRUCTIONS OPUS 910 Thank you for selecting the Opus 910 wireless system. Please take some time to read carefully through this manual before setting up the equipment. Important: • When you unpack the product, inspect it for transport damage. If you do find transport damage, notify the transportation company without delay. Delay in reporting transport damage could result in the loss of your rights to compensation. Receiver • READ these instructions. • KEEP these instructions. • HEED all warnings. • Follow all instructions. • Do not use this apparatus near water. • Clean only with a dry cloth. • Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. • Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. • Do not defeat the safety purpose of the polarised or grounding-type plug. A polarised plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. • Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. • Only use attachements/accessories specified by the manufacturer. • Use only with the cart, stand, tripod, bracket or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. • Unplug this apparatus during lightning storms or when unused for long periods of time. • Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. • The equipment must be set up so that the mains switch, mains plug and all connection on the rear of the device are easily accessible. • The equipment must be connected to a mains socket that has an earth contact. • Never expose the equipment to rain or a high level of humidity. For this reason do not install it in the immediate vicinity of swimming pools, showers, damp basement rooms or other areas with unusually high atmospheric humidity. • Do not use the device/s outside. WARNING:To reduce the risk of fire or electric shock, do not expose this/these device/s to rain or moisture. • Never place objects containing liquid (e.g. vases or drinking glasses) on the equipment. Liquids in the equipment could cause a short circuit. • Lay all connection cables so that they do not present a trip hazard. • Check whether the connection figures comply with the existing mains supply. Serious damage could occur due to connecting the system to the wrong power supply. An incorrect mains voltage could damage the equipment or cause an electric shock. Important Safety Instructions 5 Transmitter • Protect the transmitter from moisture and sudden impacts. You could either injure yourself or others or damage the transmitter. • Do not blow into the microphone. In a condenser microphone this could damage the transformer. It is preferable to carry out a speech trial. • Clip-on microphones are often very compact. If they are accidentally swallowed there is a risk of choking. Always keep this type of microphone away from small children. • Always switch off the transmitter before charging or changing the battery. • If the transmitter is fitted with a normal battery, never charge it in the charging unit. The transmitter or the batteries could be destroyed. There is a risk of explosion. • The normal commercial 9 V alkaline batteries can have a length tolerance of 2 - 3 mm. When changing the battery always ensure good contact. • From time to time the battery contacts should be cleaned with a soft cloth moistened with spirits or alcohol. • If the transmitter is not being used for weeks or months, please remove the batteries. Batteries can leak when not being used for a long time and corrode the conductor strips and components. Repair is not then possible. In this case all warranty claims are null and void. The description “leak proof” on batteries is no guarantee that they will not run out. • Never take batteries apart yourself. The battery acid contained will damage skin and clothing. • Do not throw used batteries into the domestic rubbish, but hand them in to local collectionpoints. • This equipment needs adequate ventilation. Do not cover ventilation grilles. If the heat it generates cannot be dissipated, the equipment could be damaged or flammable materials in its immediat…
